09:16 <jtojnar> fpletz: any progress on the pinentry thing? I keep running into issues that could be solved by it

09:29 <__Sander__> sigh

09:29 <__Sander__> optional dependencies are one of the weirdest things in NPM

09:29 <__Sander__> maybe even stranger than peer dependencies

10:12 orivej has joined #nixos-dev

10:39 <adisbladis[m]> __Sander__: Yeah.. In pnpm2nix I always install optional dependencies :P

10:49 chaker has joined #nixos-dev

10:50 <chaker> Hey, what's the best way to test changes to Hydra (the queue-runner to be specfic), without actually deploying it.

10:59 <LnL> the nix build runs a testsuite (not sure what's tested)

11:00 <LnL> and the nixos test on master tests a jobset eval + build now

11:01 <chaker> The test suits didn't pass Since Oct 2017. Also the build of master is broken now :/

11:03 <LnL> ?

11:04 <chaker> https://hydra.nixos.org/eval/1464543

11:04 <LnL> https://hydra.nixos.org/build/76223579

11:13 <niksnut> yeah, I've been meaning to fix that...

11:13 <chaker> Yeah, but that's the build of https://github.com/NixOS/hydra/commit/b7bc4384b7b471d1ddf892cb03f16189a66d5a0d the tip of master is broken. Just sharing for information ;). For the test I think I could create some dummy database and start the queue-runner with that. I just was wondering whether there's something easier ;)

11:14 <niksnut> chaker: you should be able to run everything without installing

11:14 <niksnut> i.e. do a nix-shell, run configure; make

11:14 <LnL> I'm guessing master needs a nixUnstable bump then

11:14 <niksnut> then run hydra-queue-runner, hydra-server etc. from the command line

11:15 <niksnut> you may want to go back to rev b11789f39993c614e53da39c29711b63cd266291 to avoid the breakage

11:15 <chaker> That's what I'm about to do. Thanks guys.

11:15 <niksnut> also you'll want to run postgres and create a local hydra db

11:16 <LnL> oh, or an older one...

11:17 <chaker> Yeah, working on creating a small dump form our Hydra instance. I don't want to load the whole database on my poor machine.

13:07 <chaker> is $src required in the derivation when running nix-shell?

13:09 <chaker> in Hydra release.nix we have "src = if shell then null else hydraSrc;" And nix-shell fails with "variable $src or $srcs should point to the source"

20:18 <copumpkin> how is the /run/keys is accessible to the "keys" group thing implemented?

20:18 <copumpkin> I see that the mount for that has gid=<keys gid> on it

20:19 <copumpkin> but I'm not sure that's having the desired effect

20:21 <copumpkin> like this thing: https://github.com/NixOS/nixpkgs/blob/666d9c09c1880c41a88426a3436b510ea1c8c272/nixos/modules/tasks/filesystems.nix#L307

20:25 <copumpkin> oh :( https://github.com/NixOS/nixops/blob/884d6c3994b227eb09c307e5d25d6885c9af8220/nixops/backends/__init__.py#L267-L269

20:25 <copumpkin> that really seems like it belongs on the nixos side of things, not in nixops

22:36 <Mic92> Is the closure size really that important, that we need it in the pull request template?

22:36 <Mic92> I mean, it could be mentioned in CONTRIBUTING.md

22:37 <gchristensen> it was added to the PR template?

22:37 <Mic92> https://github.com/NixOS/nixpkgs/commit/bf1c28e978149e586206af642808aee113156b0a

22:38 * gchristensen can't look, 56kbps

22:38 <Mic92> +- [ ] Determined the impact on package closure size (by running `nix path-info -S` before and after)

22:39 <gchristensen> ah

22:40 <gchristensen> something for borg to do maybe :)

22:41 <MichaelRaskin> Relatively to nixpkgs-unstable?

22:41 <Mic92> I would rather add a second checkbox, if people have really tested the binary :)

22:42 <gchristensen> :D

22:44 <samueldr> or a tool a bit like how `nox review` (seemed) to work, given two commitish, does this and a couple things (like nox preview?)?

22:44 <MichaelRaskin> Then you will ask for a third checkbox, if in the process of testing the submitter had any idea what the binary should actually do.

22:44 <samueldr> (never really did nox preview since I always comitted before and never really figured out how to use it with comitted changes)

22:45 <samueldr> ^ that may be useful

22:45 <samueldr> :)

22:45 <Mic92> samueldr: you can also use nix-review on pull requests.

22:45 <Mic92> it runs also faster

22:45 <Mic92> (if you have already commited the stuff)

22:45 <samueldr> never head of it

22:46 <Mic92> https://github.com/Mic92/nix-review

22:46 <samueldr> oh, wow

22:46 <samueldr> google REALLY doesn't want to let me know about it

22:46 <Mic92> oh, just noticed that I broke the build yesterdasy

22:46 <samueldr> https://stuff.samueldr.com/screenshots/2018/06/20180621184621.png

22:46 <samueldr> thanks Mic92, I'll be sure to test it :)

22:50 <Mic92> samueldr: it is part of nixpkgs
